Excel Formula to Calculate Values

[LauraEdson10]

I have a Excel Document with two tabs. The first tab is a commission log where I calculate the amount of commission payable and the date it was then paid to the person.

I then have a second tab for the statistics so it counts how many orders were generated in a particular month (formula already done for this using COUNTIF) but then I wanted a formula where if a commission payment was made within October 2019 for example, it would add up the total values for that particular month. There could be one payment per month or several. The payment will always be made on 21st of each month.

For example, where payments in a column are 21/10/2019, look up the values in the next column and add them together.

21/10/2019 - £500
21/10/2019 - £250
21/11/2019 - £400

For October 2019, it would only then take 2 payments into consideration and therefore come back with a value of £750.

Hopefully this makes sense?

Not sure if this will work but, try

=SUMPRODUCT((TEXT(Sheet2!A$1:A$1000,"mmmm yyyy")=A1&" "& B1)*(Sheet2!B$1:B$1000))

where Sheet2 has dates in column A and values in column B
and Sheet1!A1 is a month (October) and B1 is a 4 digit year

If I understand you correctly, this would solve it. Date is column A and amount in column B and reference date is in D1.

={SUM(IF(A1:A3=D1;B1:B3))}

Make sure to hold down 'Shift' before you press enter when saving the formula. Search 'Array formula' for more information.
